复选框列表选择 [英] check box list selection

问题描述

我绑定数据列表中的复选框列表，并用一个复选框显示州和城市..选中一个特定的复选框后，它应该显示该特定城市下的所有朋友....例如:如果我单击bangalore，karnataka，则应在bangalore中显示所有朋友的名字.

解决方案

使用将AutoBostBack属性设置为true的CheckBoxList和将UpdatePanel设置为UpdateMode属性设置为条件"并包含显示面板.

1.将复选框列表注册为异步回发控件.
2.当复选框列表进行回发时，使用SelectedValue属性加载好友集并更新面板.

u hv fire query
从ur表中选择名称，其中city =&checkedboxlist1.text
它将选择颗粒记录的一个值

I am binding check box list in datalist and displaying state and city with a check box.... after selecting one particular checkbox then it should display all friends which are under particular city.... ex: if i click on bangalore,karnataka then it should display all friends name within bangalore

解决方案

use a CheckBoxList with AutoBostBack property set to true, and an UpdatePanel with UpdateMode property set to Conditional and containing the displaying panel.

1. Register the checkbox list as an asynchronous post-back control.
2. when the checkbox list makes a post-back use the SelectedValue Property to load the friend set and update the panel.

u hv fire query
select name from ur table where city=" &checkedboxlist1.text
it will select the one value of particulate record
